ISL6410, ISL6410A

Single Synchronous Buck Regulators with Integrated FET

DATASHEET

The ISL6410, ISL6410A are synchronous current-mode

PWM regulators designed to provide a total DC-DC solution

for microcontrollers, microprocessors, CPLDs, FPGAs, core

processors/BBP/MAC, and ASICs. The ISL6410 should be

selected for applications using 3.3V ±10% as an input

voltage and the ISL6410A in applications requiring 5.0V

±10%.

These synchronous current mode PWM regulators have

integrated N- and P-Channel power MOSFETs and provide

pre-set pin programmable outputs. Synchronous rectification

with internal MOSFETs is used to achieve higher efficiency

and a reduced external component count. The operating

frequency of 750kHz typical allows the use of small inductor

and capacitor values. The device can be synchronized to an

external clock signal in the range of 500kHz to 1MHz. A

power good signal “PG” is generated when the output

voltage falls outside the regulation limits. Other features

include overcurrent protection and thermal overload

shutdown. The ISL6410, ISL6410A are available in an

MSOP 10 lead package.

*For tape and reel, add “-T”, “-TK” or “-T5K” suffix.

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J Std-020B.
